SAM3S4B + CDC USB Driver + Windows + Hyperterminal

Wed Jan 04, 2012 10:31 pm

Using a modified CDC Serial Driver example I am able to use the CDC example under linux with minicom and on my Mac with minicom as well. However, on Windows XP after installing the 6119.inf and the Com port showing up at Com7, I am unable to open Com7 at any baud rate. 8 data bits, no parity, and no flow control settings are used. I simply get "Unable to open COM7. Please check your port settings". In the Device Manager of the control panel I see "AT91 USB to Serial Converter (COM7)" with no error or warnings. So, clearly the windows driver is installed and recognizing the SAM3S4B. Has anyone else had any success with using the CDC driver/example under Windows?
